Did some digging around this morning.
It is looking like the 3.42 14 bolt that has the 2.5" brakes I want to transfer may be from a P30 Van. Drum is just shy of 6.5" tall. It has a casting number of 3993578K4 on it, but a Google search turns up nothing. It also has something like F/21 or F721 cast on one of the tabs and then a disconnected 3 nearby.
It would be nice to know what year the parts are.
The shoes look pretty much identical to the 3.5" shoes except for the width.
Pics I took this morning...
